  • Patent number: 5483647
    Abstract: A hybrid system environment includes a proprietary operating system and processing unit and a non-proprietary operating system (UNIX based) and processing unit. The systems tightly couple to a system bus in common with a main memory and a number of multiline communications controllers and communicate through a common area of main memory. The UNIX terminal connections to such controllers are virtual connections applied by a virtual terminal driver through the system proprietary communications software components. These components include a server, a network terminal driver (NTD) and a number of multiplexer driver modules. A multiplexer physical terminal driver is included in the UNIX-based operating system and a switching mechanism is incorporated into the virtual terminal driver for enabling switching to such physical terminal driver when a user switches via a switch command to the UNIX-based operating system.

  • Patent number: 5468967
    Abstract: A parabolic reflector and an inclined planar light reflector in a cathodoluminescence detector are integrated with a set of photo-sensitive solid-state detector cells mounted in quadrature on a supporting plate, and supported by an electron microscope vacuum chamber specimen stage adaptor unit. Designed for CL emission operation in an electron microscope, the parabolic light reflector, the inclined planar light reflector and the photo-sensitive, solid-state detector cells are optically aligned and mechanically combined through the supporting plate of the detector cells. A readily exchangeable unit is thus obtained. The unit is further supported by the specimen stage adaptor unit so as to obtain a mechanical unit which can easily be mounted in and removed from any standard electron microscope vacuum chamber stage as a single integrated unit.

  • Patent number: 5464777
    Abstract: A method for the determination of protein and creatinine in urine. An organic acid, in the form of its lithium salt, is dried onto a suitable substrate in the second reaction zone of a reaction vessel having a first reaction zone for the immunometric determination of the protein and a second reaction zone for the colorimetric determination of creatinine. After completion of the immunometric determination of the protein the dried organic salt is contacted with the urine containing creatinine resulting in solubilization of the organic acid salt as creatinine reactive reagent thereby facilitating the colorimetric determination of the creatinine.

  • Patent number: 5463762
    Abstract: Apparatus is provided for use in an Input/Output (I/O) subsystem. The I/O subsystem is coupled to a serial data transfer medium that transmits data from a sender to a recipient. The I/O subsystem processes a frame comprising user defined data and frame control data. The frame is received over the serial data transfer medium. The apparatus includes a mechanism for receiving and validating the frame from the serial data transfer medium. The receiving mechanism transmits the user defined data to a first-in, first-out (FIFO) buffer. A mechanism is provided for forming a block header. The block header comprises control data that are used by the recipient of the user defined data. The block header forming mechanism is distinct from the FIFO buffer. A switching mechanism is coupled to receive the block header and a subset of the user defined data. The recipient has a parallel storage medium.

  • Patent number: 5460048
    Abstract: An ultrasonic sensor having a polarization maintaining fibre including two orthogonal linear principal axes and a straight sensing portion. A laser source directs a beam through a quarter wave plate to provide a circularly polarized beam to an input end of the fibre. The beam emerging from an output end of the fibre is directed to a linear polarizer and the intensity of the beam is detected by a photodetector. A signal processor thereafter generates suitable driving signals for a display unit indicative of mode coupling induced in the fibre by incident ultrasonic waves.

  • Patent number: 5442576
    Abstract: A multibit shifting apparatus (50) of a data processor (40) includes a multiplier (55) such as a modified Booth's recoded multiplier for use in normal multiplication operations. The multibit shifting apparatus (50) also uses the multiplier (55) to perform programmable left and right shifts in order to save circuit area. During a shift operation, a remapping circuit (54) receives a shift count, and remaps the shift count according to a shift direction to provide a remapped signal. The multiplier (55) receives both a shift operand and the remapped signal at inputs thereof. The multiplier (55) provides a first shift result at its output. In one embodiment, an output shifter (57) shifts the first shift result by a fixed amount selectively according to the shift direction to provide a second shift result. The second shift result includes outputs of both left and right shifts in common bit positions.

  • Patent number: 5436860
    Abstract: A combined multiplier/shifter (150) uses an existing high-speed multiplier to perform both multiplies and programmable left and right shifts without a dedicated high-speed shifter. A shift decoder (160) used in a shift mode provides first recoded signals according to a shift count and a shift direction. A recoder (161) recodes a multiplier input in a multiply mode to provide second recoded signals. A multiplier array (163) receives either a multiplicand or a shift operand at its multiplicand input, and uses either the first or second recoded signals selectively according to the mode. An output of the multiplier array (163) is either a product in the multiply mode or a first shift result in the shift mode. An output shifter (157) selectively adjusts the first shift result according to the shift direction to provide a second, final shift result.

  • Patent number: 5430393
    Abstract: An integrated circuit (40) has a low-power mode in which at least one switched inverter stage (60) of a clock amplifier (41) is disabled in response to a stop signal. The stop signal indicates that the integrated circuit (40) is in low-power mode. In one embodiment, each switched inverter stage is a complementary metal-oxide-semiconductor (CMOS) switched inverter (60), in which an additional P-channel transistor (61) is connected between the source of an inverter P-channel transistor (62) and a positive power supply voltage terminal, and in which an additional N-channel transistor (64) is connected between a source of an inverter N-channel transistor (63) and a negative power supply voltage terminal. A non-switched inverter stage (52) remains active during low-power mode to maintain a DC value of a clock input signal near a switchpoint of the clock amplifier (41).

  • Patent number: 5413836
    Abstract: A frame which is configured by means of a number of extrusions, a number of links, a number of bolts, a number of nuts and a number of nut positioners. Each link defines a number of holes. Each extrusion defines at least one longitudinal channel being cruciform as shown in a cross-sectional view taken on a plane intersecting the extrusion. Each nut positioner defines a recess so that the nuts are kept from rotating in the recess and a profile so that it can be positioned at any desired point in the channels. A number of bolts are inserted through the holes formed in each link and further secured in the nuts retained in the channels formed in a number of extrusions. Each link can be attached to a number of extrusions. Thus, a frame can be configured by means of a number of extrusions.
